Research, reading and note making are essential skills for A level Biology study. For the following task you are going to produce ‘Cornell Notes’ to summarise your reading.

1. Divide your page into three sections like this

2. Write the name, date and topic at the top of the page

3. Use the large box to make notes. Leave a space between separate idea. Abbreviate where possible.

4. Review and identify the key points in the left hand box

5. Write a summary of the main ideas in the bottom space

The Big Picture is an excellent publication from the Wellcome Trust. Along with the magazine, the company produces posters, videos and other resources aimed at students studying for GCSEs and A level.For each of the following topics, you are going to use the resources to produce one page of Cornell style notes.Use the links of scan the QR code to take you to the resources.

Topic 1: The CellAvailable at: http://bigpictureeducation.com/cellThe cell is the building block of life. Each of us starts from a single cell, a zygote, and grows into a complex organism made of trillions of cells. In this issue, we explore what we know – and what we don’t yet know – about the cells that are the basis of us all and how they reproduce, grow, move, communicate and die.

Topic 2: The Immune SystemAvailable at: http://bigpictureeducation.com/immuneThe immune system is what keeps us healthy in spite of the many organisms and substances that can do us harm. In this issue, explore how our bodies are designed to prevent potentially harmful objects from getting inside, and what happens when bacteria, viruses, fungi or other foreign organisms or substances breach these barriers.

Topic 3: Exercise, Energy and MovementAvailable at: http://bigpictureeducation.com/exercise‐energy‐and‐movementAll living things move. Whether it’s a plant growing towards the sun, bacteria swimming away from a toxin or you walking home, anything alive must move to survive. For humans though, movement is more than just survival – we move for fun, to compete and to be healthy. In this issue we look at the biological systems that keep us moving and consider some of the psychological, social and ethical aspects of exercise and sport.


Topic 4: PopulationsAvailable at: http://bigpictureeducation.com/populationsWhat’s the first thing that pops into your mind when you read the word population? Most likely it’s the ever‐increasing human population on earth. You’re a member of that population, which is the term for all the members of a single species living together in the same location. The term population isn’t just used to describe humans; it includes other animals, plants and microbes too. In this issue, we learn more about how populations grow, change and move, and why understanding them is so important.

Topic 4: PopulationsAvailable at: http://bigpictureeducation.com/health‐and‐climate‐changeThe Earth’s climate is changing. In fact, it has always been changing. What is different now is the speed of change and the main cause of change – human activities. This issue asks: What are the biggest threats to human health? Who will suffer as the climate changes? What can be done to minimise harm? And how do we cope with uncertainty?


A level Biology will use your knowledge from GCSE and build on this to help you understand new and more demanding

ideas. Complete three of the following tasks to make sure your knowledge is up to date and you are ready to start studying:

DNA and the Genetic Code

In living organisms nucleic acids (DNA and RNA have important roles and functions related to their properties. The sequence

of bases in the DNA molecule determines the structure of proteins, including enzymes.

The double helix and its four bases store the information that is passed from generation to generation. The sequence of the

base pairs adenine, thymine, cytosine and guanine tell ribosomes in the cytoplasm how to construct amino acids into

polypeptides and produce every characteristic we see. DNA can mutate leading to diseases including cancer and sometimes

anomalies in the genetic code are passed from parents to babies in disease such as cystic fibrosis, or can be developed in

unborn foetuses such as Downs Syndrome.

Read the information on these websites (you could make more Cornell notes if you wish):

And take a look at these videos:

http://ed.ted.com/lessons/the‐twisting‐tale‐of‐dna‐judith‐hauck

http://ed.ted.com/lessons/where‐do‐genes‐come‐from‐carl‐zimmer

Task:

Produce a wall display to put up in your classroom in September. You might make a poster or do this using PowerPoint or

similar Your display should use images, keywords and simple explanations to:

Define gene, chromosome, DNA and base pair

Describe the structure and function of DNA and RNA

Explain how DNA is copied in the body

Outline some of the problems that occur with DNA replication and what the consequences of this might be.

Evolution

Transfer of genetic information from one generation to the next can ensure continuity of species or lead to variation within

a species and possible formation of new species. Reproductive isolation can lead to accumulation of different genetic

information in populations potentially leading to formation of new species (speciation). Sequencing projects have read the

genomes of organisms ranging from microbes and plants to humans. This allows the sequences of the proteins that derive

from the genetic code to be predicted. Gene technologies allow study and alteration of gene function in order to better

understand organism function and to design new industrial and medical processes.

http://ed.ted.com/lessons/the‐race‐to‐sequence‐the‐human‐genome‐tien‐nguyen

Task:

Produce a one page revision guide for an AS Biology student that recaps the key words and concepts in this topic. Your

revision guide should:

Describe speciation

Explain what a genome is

Give examples of how this information has already been used to develop new treatments and technologies.


Biodiversity

The variety of life, both past and present, is extensive, but the biochemical basis of life is similar for all living things.

Biodiversity refers to the variety and complexity of life and may be considered at different levels. Biodiversity can be

measured, for example within a habitat or at the genetic level. Classification is a means of organising the variety of life

based on relationships between organisms and is built around the concept of species. Originally classification systems were

based on observable features but more recent approaches draw on a wider range of evidence to clarify relationships

between organisms. Adaptations of organisms to their environments can be behavioural, physiological and anatomical.

Adaptation and selection are major factors in evolution and make a significant contribution to the diversity of living

organisms.

http://ed.ted.com/lessons/why‐is‐biodiversity‐so‐important‐kim‐preshoff

http://ed.ted.com/lessons/can‐wildlife‐adapt‐to‐climate‐change‐erin‐eastwood

Task:

Write a persuasive letter to an MP, organisation or pressure group promoting conservation to maintain biodiversity.

Your letter should:

Define what is meant by species and classification

Describe how species are classified

Explain one way scientists can collect data about a habitat, giving an example

Explain adaptation and how habitat change may pose a threat to niche species

Exchange and Transport

Organisms need to exchange substances selectively with their environment and this takes place at exchange surfaces.

Factors such as size or metabolic rate affect the requirements of organisms and this gives rise to adaptations such as

specialised exchange surfaces and mass transport systems. Substances are exchanged by passive or active transport across

exchange surfaces. The structure of the plasma membrane enables control of the passage of substances into and out of

cells

http://ed.ted.com/lessons/what‐do‐the‐lungs‐do‐emma‐bryce

Task:

Create a poster or display to go in your classroom in September. Your poster should either: compare exchange surfaces

in mammals and fish or compare exchange surfaces in the lungs and the intestines. You could use a Venn diagram to do

this. Your poster should:

Describe diffusion, osmosis and active transport

Explain why oxygen and glucose need to be absorbed and waste products removed

Compare and contrast your chosen focus.


Cells

The cell is a unifying concept in biology, you will come across it many times during your two years of A level study.

Prokaryotic and eukaryotic cells can be distinguished on the basis of their structure and ultrastructure. In complex

multicellular organisms cells are organised into tissues, tissues into organs and organs into systems. During the cell cycle

genetic information is copied and passed to daughter cells. Daughter cells formed during mitosis have identical copies of

genes while cells formed during meiosis are not genetically identical

Task:

Produce a one page revision guide to share with your class in September summarising one of the following topics: Cells

and Cell Ultrastructure, Prokaryotes and Eukaryotes, or Mitosis and Meiosis.

Whichever topic you choose, your revision guide should include:

Key words and definitions

Clearly labelled diagrams

Short explanations of key ideas or processes.

Biological Molecules

Biological molecules are often polymers and are based on a small number of chemical elements. In living organisms

carbohydrates, proteins, lipids, inorganic ions and water all have important roles and functions related to their properties.

DNA determines the structure of proteins, including enzymes. Enzymes catalyse the reactions that determine structures

and functions from cellular to whole‐organism level. Enzymes are proteins with a mechanism of action and other

properties determined by their tertiary structure. ATP provides the immediate source of energy for biological processes.

Task:

Krabbe disease occurs when a person doesn’t have a certain enzyme in their body. The disease effects the nervous

system. Write a letter to a GP or a sufferer to explain what an enzyme is.

Your poster should:

Describe the structure of an enzyme

Explain what enzymes do inside the body


Ecosystems

Ecosystems range in size from the very large to the very small. Biomass transfers through ecosystems and the efficiency of

transfer through different trophic levels can be measured. Microorganisms play a key role in recycling chemical elements.

Ecosystems are dynamic systems, usually moving from colonisation to climax communities in a process known as

succession. The dynamic equilibrium of populations is affected by a range of factors. Humans are part of the ecological

balance and their activities affect it both directly and indirectly. Effective management of the conflict between human

needs and conservation help to maintain sustainability of resources.

Task:

Produce a newspaper or magazine article about one ecosystem (e.g. the arctic, the Sahara, the rainforest, or something

closer to home like your local woodland, nature reserve or shore line).

Your article should include:


Pictures or diagrams of your chosen ecosystem.

A description of the changes that have occurred in this ecosystem

An explanation of the threats and future changes that may further alter this ecosystem.

Control Systems

Homeostasis is the maintenance of a constant internal environment. Negative feedback helps maintain an optimal internal

state in the context of a dynamic equilibrium. Positive feedback also occurs. Stimuli, both internal and external, are

detected leading to responses. The genome is regulated by a number of factors. Coordination may be chemical or

electrical in nature

Control, Water and the Kidneys, Glucose, or The Liver.

Whichever topic you choose, your poster or display should include:


Clearly labelled diagrams

Short explanations of key ideas or processes.


Energy for Biological Processes

In cellular respiration, glycolysis takes place in the cytoplasm and the remaining steps in the mitochondria. ATP synthesis is

associated with the electron transfer chain in the membranes of mitochondria and chloroplasts in photosynthesis energy is

transferred to ATP in the light‐ dependent stage and the ATP is utilised during synthesis in the light‐independent stage.

Remember there are also lots of zoos, wildlife and safari parks across the country, here are some you may not have heard of or considered:

Colchester Zoo, Cotswold Wildlife Park, Banham Zoo (Norfolk), Tropical Birdland (Leicestershire), Yorkshire

Wildlife Park, Peak Wildlife Park, International Centre for Birds of Prey (York), Blackpool Zoo, Beale Park (Reading)

There are also hundreds of nature reserves (some of which are free) located all over the country including:

RSPB sites at Lochwinnoch, Saltholme, Fairburn Ings, Old Moor, Conwy, Minsmere, Rainham Marshes, Pulborough

Brooks, Radipole Lake, Newport Wetlands.

Wildlife Trust Reserves and others at Rutland Water, Pensthorpe, Insh Marshes, Attenborough Centre, Inversnaid,

Skomer, Loch Garten, Donna Nook, Chapmans Well, Woodwalton Fen, London Wetland Centre, Martin Down and

Woolston Eyes Reserve.

Many organisations also have opportunities for people to volunteer over the summer months, this might include

working in a shop/café/visitor centre, helping with site maintenance or taking part in biological surveys. Not only

is this great experience, it looks great on a job or UCAS application.

For opportunities keep an eye out in your local press, on social media, or look at the websites of organisations like

the RSPB, Wildlife Trust, National Trust or Wildlife & Wetland Trust.

There are also probably lots of smaller organisations near you who would also appreciate any support you can

give!

Science on Social Media


These websites all offer an amazing collection of resources that you should use again and again through out your course.

At GCSE you learnt how genetic diseases are inherited. In this virtual fly lab you get to breed fruit flies to investigate how different features are passed on. http://sciencecourseware.org/vcise/drosophila/

Probably the best website on Biology….Learn Genetics from Utah University has so much that is pitched at an appropriate level for you and has lots of interactive resources to explore, everything from why some people can taste bitter berries to how we clone mice or make glow in the dark jelly fish. http://learn.genetics.utah.edu/

Ok, so not a website, but a video you definitely want to watch. One of the first topics you will learn about is the amazing structure of the cell. This BBC film shows the fascinating workings of a cell… a touch more detailed than the “fried egg” model you might have seen. http://www.dailymotion.com/video/xzh0kb_the‐hidden‐life‐of‐the‐cell_shortfilmsIf this link expires – google “BBC hidden life of the cell”

In the summer you will most likely start to learn about Biodiversity and Evolution. Many Zoos have great websites, especially London Zoo. Read about some of the case studies on conservation, such as the Giant Pangolin, the only mammal with scales. https://www.zsl.org/conservation

DNA from the beginning is full of interactive animations that tell the story of DNA from its discovery through to advanced year 13 concepts. One to book mark! http://www.dnaftb.org/

Science websites


Day 4 of the holidays and boredom has set in?

There are loads of citizen science projects you can take

part in either from the comfort of your bedroom, out

and about, or when on holiday. Wikipedia does a

comprehensive list of all the current projects taking

place. Google ‘citizen science project’

Want to stand above the rest when it comes to UCAS? Now is the time to

act.

MOOCs are online courses run by nearly all Universities. They are short FREE

courses that you take part in. They are usually quite specialist, but aimed at

the public, not the genius!

There are lots of websites that help you find a course, such as edX and Future

learn.

You can take part in any course, but there are usually start and finish dates.

They mostly involve taking part in web chats, watching videos and

interactives.

Completing a MOOC will lookgreat on your Personalstatement and they are deadeasy to take part in!

Science: Things to do!
